Questioning beyond the Book in Teacher-Child Reading: The Effect of High Cognitively Demanding Questions on Children’s Vocabulary Growth

Shared book reading (SBR) is considered the standard in fostering preschool children’s oral language skills. However, research has emphasized that extratextual conversation around book reading (i.e., questions, comments, and statements outside the actual reading), in particular, is related to effective book reading because it provides children with the opportunity to interact with word and word meanings beyond the text. The present dissertation examines how teacher questioning around SBR, and particularly high cognitive demand questions, impact children’s vocabulary growth. No reviews of the research have been conducted on the effect of cognitive complexity of questions around SBR on preschoolers’ vocabulary knowledge. Therefore, the second chapter of this dissertation presents a systematic literature review that summarizes and identifies the similarities and differences among studies of questions shared book reading conducted in recent years. The review revealed that the effect of cognitive complexity of questions around SBR on preschoolers’ vocabulary knowledge is limited, and the findings are not conclusive. The third chapter consists of an observational study that examined how the cognitive complexity of teacher-generated questions around SBR was associated with preschoolers’ receptive and expressive vocabulary knowledge. The sample consisted of 100 children nested under 13 teachers who were part of a larger vocabulary intervention study in which small groups of children participated in 18 weeks of 5-day instructional shared reading cycles of approximately 20-minutes. The teachers followed a well-scripted curriculum, but for purposes of the present study only spontaneous, unscripted teacher questions around SBR were considered. The reading sessions were video recorded, and teachers’ questions were coded according a rubric that evaluated cognitive demand level (four levels, from labeling to associating words and concepts) using The Observer XT (Noldus Information Technology, 2013). It was hypothesized that teachers who asked more spontaneous questions than required by the curriculum (i.e., unscripted questions) would be more effective at increasing children’s vocabulary learning. It was also hypothesized that cognitively demanding questions would be associated with higher word learning among children. Contrary to the expectations, the frequency and duration of all unscripted questions did not predict expressive nor receptive children’s vocabulary knowledge on standardized or researcher-developed measured. However, the duration of questions that placed high cognitive demands on the children predicted their scores on a standardized test of expressive vocabulary

A design process for harware/software system co-design and its application to designing a reconfigurable FPGA

This paper is going to address the topic of hardware/software systems co-design. The paper will develop two points of view. First, it provides a system-theoretical layout on the problem of designing hardware-software systems. This layout will enable the designer to proceed systematically in optimizing the tradeoff between the desired functionality, available resources and operating conditions. Second, the paper will describe an application of some of the theoretical principles to the design of an embedded automotive system built on a low-cost FPGA

A Tentative Study of the Effects of Heat-Inactivation of the Probiotic Strain Shewanella putrefaciens Ppd11 on Senegalese Sole (Solea senegalensis) Intestinal Microbiota and Immune Response

ABSTRACT: Concerns about safety, applicability and functionality associated with live probiotic cells have led to consideration of the use of non-viable microorganisms, known as paraprobiotics. The present study evaluated the effects of dietary administration of heat-inactivated cells of the probiotic strain Shewanella putrefaciens Ppd11 on the intestinal microbiota and immune gene transcription in Solea senegalensis. Results obtained were evaluated and compared to those described after feeding with viable Pdp11 cells. S. senegalensis specimens were fed with basal (control) diet or supplemented with live or heat inactivated (60 °C, 1 h) probiotics diets for 45 days. Growth improvement was observed in the group receiving live probiotics compared to the control group, but not after feeding with a probiotic heat-inactivated diet. Regarding immune gene transcription, no changes were observed for tnf?, il-6, lys-c1, c7, hsp70, and hsp90aa in the intestinal samples based on the diet. On the contrary, hsp90ab, gp96, cd4, cd8, il-1?, and c3 transcription were modulated after probiotic supplementation, though no differences between viable and heat-inactivated probiotic supplemented diets were observed. Modulation of intestinal microbiota showed remarkable differences based on the viability of the probiotics. Thus, higher diversity in fish fed with live probiotic cells, jointly with increased Mycoplasmataceae and Spirochaetaceae to the detriment of Brevinemataceae, was detected. However, microbiota of fish receiving heat-inactivated probiotic cells showed decreased Mycoplasmataceae and increased Brevinemataceae and Vibrio genus abundance. In short, the results obtained indicate that the viable state of Pdp11 probiotic cells affects growth performance and modulation of S. senegalensis intestinal microbiota. On the contrary, minor changes were detected in the intestinal immune response, being similar for fish receiving both, viable and inactivated probiotic cell supplemented diets, when compared to the control dietThis study was supported by MINECO (grant no.
